surface failure of rock

The basic slope failure pattern of tension fissure-circular surface slip-plane failure is obtained for study of slope failure of flat rock strata by use of double bottom friction model by which the difference in strength of various rocks can be reflected.

采用双层底面摩擦模型，研究近水平岩层边坡破坏模式，能体现出不同岩体在强度上的差异，得到近水平岩层边坡破坏为张裂缝圆弧面平面的边坡滑动破坏的基本模式。

The stress on the rock slip surface is analyzed and the course of the failure of the slop is pointed out Furthermore, the method of preventing the failure is introduced Finally, the random geologic parameters analysis is discussed

对岩石滑移面上的应力进行分析，说明形成滑移面破坏的原因，提出了相应的处理方法，并对随机性的地质参数进行分析和探讨
